Using linear functions, it is found that Rowan and Kennedy will have read the same number of pages in 10 minutes.
What is a linear function?
- A linear function is modeled by:
In which:
- a is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0.
For Rowan, we have that:
- He has already read 20 pages, hence the y-intercept is
.
- He reads 1.5 pages per minute, hence the slope is
Then:
For Kennedy, we have that:
- He has already read 25 pages, hence the y-intercept is
.
- He reads 1 page per minute, hence the slope is
Then:
They will have read the same number of pages after x minutes, for which:
Then:

Answer: mean = 10.3 and median = 9.5
Step-by-step explanation:
Given data :
22, 14, 8, 1, 9, 0, 31, 2, 13, 3, 11, 10
Mean =
Median = Middle most value.
For Median , we first arrange the data values in an order.
0 , 1 , 2, 3, 8, 9, 10 , 11, 13 , 14, 22, 31
Since , number of data values is 12 ( even) , so the median would be the mean of the two middlemost value.
i.e . Median=
Hence, the mean and median of this distribution (in years) are :
mean = 10.3 and median = 9.5
